3. Tom Theuns, Durham Motivation Stars form in GMCs, but: these are difficult to resolve in cosmological simulations have extra physics which is difficult to include include GMCs using subgrid physics

4. Tom Theuns, Durham Physics to model:

5. Tom Theuns, Durham Starformation & Molecular Cloud Implementation: Molecular clouds represented by ‘sticky particles’ decoupled from SPH Sticky particle represents spectrum of molecular clouds cloud-cloud interaction same a sticky-particle -- sticky-particle interaction Stars form in GMCs (mass cloud > M_*) Ambient & hot gas simulated with SPH (Gadget2)

6. Tom Theuns, Durham One-zone model Resolution Mass-spectrum

7. Tom Theuns, Durham Feedback: Starformation destroys parent GMC Compute volume of SNe bubbles using Sedov or fits from simulation, and dump SNe energy only when porosity > 1Star Hot gas / Sne evaporate clouds due to thermal conduction
